Application filed January 26, 1905. Serial No. 242,781.

1'0 all w/wrn it may concern.-

Be it known that 1, WILLIAM M. SANDERS, a citizen of the United States, residing at Kern, in the county of Nashita, Oklahoma Territory, have invented certain new and useful Improvements in VVire-Stretchers, of which the following is a specification.

This invention embodies improvements in devices for stretching line-wire of wire fences, being designed for splicing, taking up slack in the wire, or like purposes.

The invention resides more specifically in the novel arrangement and construction of the working parts of the device whereby the wirestretcher is adapted for quick application to or detachment from the wire in its actual use, the construction of the device as a whole lending great substantiality and power, which is of importance in an implement of this class.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

\Vhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features of the invention, still some of the preferred embodiments thereof are shown in the accompanying drawings, in which Figure 1 is a perspective view of a wire-- stretcher embodying the essential features of the invention. Fig. 2 is a top plan view showing one application of the invention in actual use. Fig. 3 is an enlarged sectional View, bringing out more clearly the exact construction of the clamp device or attaching means for securing the implement to the wire. Fig. 4 is a detail view of a modified form of lever. Fig. 5 is a perspective view showing aslightlymodified construction of the device, the operating-lever and the attaching connection being omitted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

in the drawings the numeral 1 designates an operating-lever having pivoted thereto spaced engaging dogs 2. The operating-lever 1 is used in connection with a notched bar 3, the notches or teeth of the bar 3 being indicated at 41- and arranged longitudinally of the bar, almost the entire length thereof. The dogs 2 are pivoted at one end to the lever 1, as shown at 5, the opposite ends of the dogs engaging the notches or teeth L of the bar 3. The dogs 2 operate upon opposite sides of the bar 3 (ordinarily the upper and lower sides) when the device is in operative position, and the engaging ends of the dogs 3 are provided with loops 6, which receive the bar 3 and serve to normally effect the engagement of the dogs with the teeth or notches 1 thereof. The normal positions of the dogs 2 are such that the engaging ends of these dogs cooperate normally with the bar 3, and one of the dogs 2 is longer than the other in order that the engaging portions of these members may not interfere one with the other in the practical operation of the device. Between the points of pivotal attachment 5 of the dogs 2 of the lever 1 and extending from the opposite sides of the lever is connected attaching means in the form of a suitable chain 9, having a hook 8 at the end thereof opposite that attached to the lever 1, so that said chain may be readily wrapped about a post in order to positively position theimplement prepara tory to stretching wire, as above mentioned. The bar 3 is also provided with suitable attach ing means at its outermost end consisting of a clamp of peculiar form which is connected with an end of the bar 3 by means of a link 8. The clamping device (indicated at 9) consists, essentially, of a wedgeshaped member 10, approximately of triangular form, connected at its smaller end with the link 8, as shown at 11, said member 10 having a clamp member 12 mounted thereon. The member 10 is of skeleton formation, and the clamp member12 is provided with a loop 12 at one end, which receives one of the side bars 10 of the member 10. The opposite end of the member 12 is provided with a hook or engaging member 13, adapted to cooperate with the side bar 10* of the member 10 opposite that upon which the clamp member is mounted, and the wire when connected with the im plement is clamped between the hook or engaging member 13 and the adjacent side bar of the wedge-shaped member 10. The side bar of the wedge-shaped member 10 with which the hook 13 engages is preferably roughened or serrated, so as to effect a greater binding action of the parts 10 and 12 in the use of the device. The clamp member 12 has a certain amount of slidable movement with reference to the member 10 to secure the necessary engaging cooperation of the parts, as above described.

In the actual use of the device the chain 7 may be wrapped about a post. and since the chain is connected with the lever 1 at a point between the dogs 2 it will be seen that a pivotal movement of the said lever may be had. The pivotal movement of the lever 1 will alternately cause the dogs 2 to engage the teeth 4 of the bar 3 and cause longitudinal movement of the bar with reference to the dogs. The bar 3, having previously been connected with the wire by means of the clamp device 9, will of course stretch the wire for the purposes of the invention in a manner clearly apparent. hen one of the dogs 2 is in positive engagement with the bar 3 to effect longitudinal movement of this bar toward the lever, the other of the dogs is advancing in an opposite direction longitudinally of the bar 3 preparatory to engaging therewith at a predetermined point to continue the movement of the bar when the direction of pressure upon the lever 1 is reversed.

Under certain conditions, especially when the device is used for splicing the ends of wire, it is necessary that the lever 1 be directly connected with an end of the wire, while the bar 3 is connected with the other end, and for this purpose one or more of the clamp devices 9 is connect-ed with the chain 7 near the lever 1, and these clamp devices would cooperate with the wire in exactly the same manner as described with reference to the clamp device carried by the notched bar 3.

In Fig. 4 of the drawings a modified form of the lever 1 is illustrated. This lever is provided with handles at opposite ends and is designed for heavy work where greater leverage or power is necessary for the purposes of the invention. The end of the bar 3 opposite that having the clamp device 9 secured thereto is provided with a cross-head 1 1, having openings 15 therethrough, through which openings the dogs 2 pass, being guided in their longitudinal movement by the crosshead aforesaid. The dogs are thus always held in proper relative position to the bar 3 both by the member 14 and the loop 6.

It is immaterial within the contemplation of the invention whether the dogs 2 be arranged above and below or upon opposite sides of the notched bar 3, and in Fig. 5 is illustrated a form of the invention in which the said dogs are spaced laterally and located to the right and to the left of the bar 3. The operatinglever is not shown in Fig. 5; but it will be understood that the same may be pivotally connected with the dogs 2 by means of boltand-nut connections or the like. Under some conditions of service the form of the device shown in Fig. 5 is especially adapted for the work; but the invention involves generally the use of the parts arranged in their relative positions as set forth in Figs. 1 and 5 of the drawings.

Having thus described the invention, what is claimed as new is 1. In a wire-stretcher, the combination of the bar 3 having the longitudinal notched portion 4;, attaching means connected with one end of the bar, the lever 1, spaced dogs carried by said lever and normally engaging the notched portion t of the bar 3 for alternate cooperation therewith, and attaching means connected with the lever between the points of connection of the dogs aforesaid.

2. In a wire-stretcher, the combination of a lever, spaced dogs extending from the lever, a notched bar operating between the dogs aforesaid and engaged thereby, attaching means carried by the notched bar, attaching means connected with the lever at a point between the points of connection of the dogs aforesaid, and guides projecting from the dogs for cooperation with the notched bar.

3. In a wire-stretcher, the combination of a lever, spaced dogs extending from the lever, a notched bar operating between the dogs aforesaid and engaged thereby, attaching means carried by the notched bar, attaching means connected with the lever at a point between the points of connection of the dogs aforesaid, and guide means independent of the lever t engaging and directing the movement of the dogs with reference to the notched bar.
